Another update:
I need to expand upon what happened at the table on Thursday night. D did ask me "how are you" and I said, good, and then he proceeded to talk to another person at the table (C, a person he knew from the past) the rest of the time he was there. When the other person left the table, he and I were alone. He did not say anything to me, so I said, How was your day and He said, he was keeping busy as agenda coordinator and he asked, how was your day and I said good. then he said, I'm going to go sit down now, it was good to see you again. So I felt like he was afraid to talk to me or something.
